Hi brianjwallace,

 

Thanks for reaching out in the Google Nest Community forum. I'd like to take a closer look at it. A few questions: what is the make and model of your system? Also, in what country are you located? If possible, could you please take a photo of the wires connected to your system's control board? Ensure that the labels of the wires are visible.

 

It looks like you have a proprietary system which isn't compatible with the Nest Thermostats. However, some proprietary systems can be rewired by a pro installer to be compatible.

 

Best,

Jenelyn
